Not only did many people nail the exact number, but even more impressively, it looks to me like the answers are pretty much centered around the right number too.
We come off looking like a pretty smart and reasonable bunch, after the fact. I think it's a testament to the quality of people who frequent the board. And, I think it's a pretty good defense against the accusation that we are all pie-eyed homers who overvalue our talent/coaching.
I went back through the thread and counted 56 guesses (excluding the two optimists who went for 82-0).
The guesses ranged from 45-61.
The mean guess was 53.6.
The median guess was 53.
The most common guess was 52.
36 out of 56 guesses were between 51-55 wins, or within two of our actual total.
Nice job being realistic, everyone!
